EYELETING-MA CHINE.

Application filed November 22,

To all whom, 'z't may concern Bc it known that I, THoMes il. HALLAM, ocitizen of the United States, residing et Lynn, in the county of Essexand State of Massachusetts, haveinvented certain Improvements inEyeleting'lvluehinos, of which the following description, in connectionwith the accompanying drawings, is o specification, ylike referencecharacters on the drawings indicating like parts in the several figures.

The present invention relates to machines for setting eyelets or similarfastening' devices and more particularly to machines for setting blindor invisible eyelets in boots and shoes. n y

In setting such eyelets it has been customary tol employ an upsetting'tool having e. shouldered upsetting surface of a diameter suiiicientlysmall to be passed through the hole which constitutes the lacing passageiin n slices of many styles, and particularly those having invisibleeyelets, 1t is desirable m passage small as possible. Consequently t 1eattempt has been made to reduce the diameter of the upsetting die to aminimum. In dealing with certain kinds of eyelets-,3' however, asmoother and more satisfactory clenehing of thc eyelet borrel is securedby the employment of al1/upsetting die having a diameter greater thunthe diameter of the lacing passage hole. In one of its important aspectsthe present invention consists in an upsetting tool having e shoulderedupsettin surface formed in a. Eile die sections. Such an upsetting diemay be inserted through a relatively small lacing passage hole und thenexpanded to such a diameter as will insure e smooth and reliableclenehing operation upon all eyelets which .may be presented forinsertion. As herein shown the upsetting tool is provided lwith a recessabove its setting shoulder in order that Vthe expanding operation maytake place witbout stretchingy the hole. This feature is not essentialin all cases but has been found desirable in handling certain classes ofwork.

Expansbleupsetting dies have been used heretofore to some extent inmachines for setting blind or invisible eyelets, In these Specificationof Letters Patent.

machines the Icxpimsible die has been utilined to remove theeyelets fromthe raceway, in this respect assuming thefunctlon usually carried out bythe spindleof the lower setting` die.. As distinguished from thisarrangement, end in accordenee` with another feature of the presentinvention, it is proposed to employ a tool distinct from the cxpansibleupsetting die for removing the eyelets from the racewey. Such anarrangement possesses the advantage lthat the upsettin die, which isnecessarily of somewhat de icate construction, is relieved of oneoperation which in the machines heretofore used has occasionally causedbreakage.

Another feature of the invention consists in an expansihle upsettingldie so constructed and arranged that its positionand movement is at alltimes positively controlled. Such construction has been lfound 'tcontribute largely to the accurate and reliable operation of themachine. f Ks herein shown the desired results are eii'ected by mountingthe cxpnnsible upsetting die ri 'diy but adjnstably in the top setholder o an eyeleting machine of well-known construction.

Still another feature of the invention consists in an expansibleupsettiu die so constructed and arranged as to e ect the automaticfeedin of the work in addition to its function o setting theeyeletsiOther features of the invention. .consist in the `combination with an'expensibl upsetting die,fof a die ex ending member constructed andarrange to' enter the 4expansible portion of the die for a substantiel`distance and so ri idly support theindividuel sections thereo Thisexpedient has `been found useful in educing the liability of breakage ofthe dien-,"1

Other feaztturesy [of the invention relate to various details `of'e'onstructiur in the lmountu ing of the expansible die and `dieexpgtnding tool. These and other featutesuthe invention will be bestunderStdDd-.hdteppre ciated from the following descri `tioitol" apreferred embodiment thereof seected .for purposes of illustration-andAshown in the accompanying' drawings; -inl Wphioh,

Fig. B is a sectional view showin the eyelet setting tools in theposition which they.

The Amac iine frame 10 is 'provided with bearings 12 in whichreciprocates a vertically movable plunger 14 having the setting oreyelet inserting dies 16 adj'ustably mounted in its upper end. Astationary work late 40 is secured to the machine frame and is cut awayto ernii't the passageof the setsharp ribs 62 which act to splitl thebarrel ting and punc ing tools. The frame also carries a swinging lever48 in which the upsetting die, to be presently described, is mounted. Atone side of the lever 48 is a second lever 44 which carries a punch 42arranged to coperate with a punching die 46 disposed beneath it in aslot in the work table 40. A presser foot 47 of the usual constructionis provided for holding the work stationary between the feeding steps. Araceway is arranged to sup ly the eye- 4lets successively to the,die 16.he actuat ing mechanism for th'e various tools is not illustrated hereinas it forms no part of theA present invention and may well be of similarconstruction to the corresponding mechanism of the Perfection eyeletingmachine.

The upsetting die comprises a tubular shank 58 merging at its lower endinto a plurality ol' resilient sections 60. Near its lower end theupsetting, die has an outwardly projecting shoulder upon the lowersurface of which is formed the upsetting surface v64. ,The upsettingsurface is recessed or corrugated to form a numberfif .of the e elet atpoints half way between the edge o each section. This insures that themetal of the eyelet barrel shall extend continuously across the openingwhich occurs between adjacent sections f the die when in expandedcondition. Above the shoulder the upsetting die is contracted indiameter' so that it may be expanded after its insertion through thework without stretching the hole.

The upsetting die is rec'eived within a. tubular holder 49 which in turnis received within a bore in the forward end of the lever 48. The holder4,9 isslitted for a portion of its length so" that it may bevcontractcd'u on the upsetting die and also held -in p ace in the lever48 by -a set screw 51. The

holder' 49 is threaded at its upper end 50 into the upper end of thebore in thel lever 48 and may be adjusted "b being turned in the properdirection. he holder 49 at its upper end 50 is also internally threadedjusting the holder 49 in the lever 48` and the upsetting die in theholderand that when such adjustments have been eected allparts arerigidly held in their adjusted positions. The eyelet insertin die 16 isprovided with a spindle 18 whic serves to remove the eyelet from theraceway, guide it to the upsetting die and also expand the upsettingdie. The upper end of the spindle is tapere and shaped to enter andexpand `the upsetting die. Below' its tapered end the spindle has acylindrical portion 20 which passes intothe expansible upsetting die fora substantial distance, as shown in Fig. 3. Below the cylindricalportion 20 the spindle has a shoulderof substantially the samediameteras the diameter of the expanded upsetting die, so that the diameter ofthe cylindrical spindle 1B is suitable for guiding an eyelet againstVthe upsetting surfaces. At its lower end the spindle is threaded into aslidable angle' ieee 24 which extends outwardly throng a slot in oneside of the plunger 414 and is guided for vertical nievement in av pathparallel to that ofthe plunger. Beneath the inwardly projecting end ofthe angle piece 24 is disposed a plunger 26 heldA normally in anelevated position by a spring 30. The plunger 26 and spring 30 areinclosed in a tubular holder 28 which initurn is movable in the bore ofthe plunger 14. The lower end of the holder 28 is shoulderedI andreduced in diameter so that it mayenter a compression spring 32 ofgreater .strength than the spring 30 above mentioned.

A plate 34 is secured to the machine frame adjacent to the plunger 14and is shaped to form a part of the bearings for the end of the anglepiece 24. vAt its upper `end the plate 34- carries an adjustable stop 36which is arranged to engage the angle piece 24 durs i ger 14 iswithdrawn through the upon the 'work table 40 with the point atp, blindey which the first 'eyelet is to be set beneath the punch 42 and theouter or leather portion 80 uppermost. The machine is then set inoperation whereupon the punch descends.

and perforates both parts of the upper. The punch is then elevated andmoved toward the rigl-it (Figsl) to an inoperative position. Theexpansiblc upsetting die is next moved into position above.- the holesthus formed and is lowered sufficiently to bring the shoulder of itsupsetting surface through the leather portion 80 and substantiallyfins-h with the inner surface of the 1ining portion 82. It is then movedtoward the left, feeding the work into the position shown in Fig. 2, thepunch 42 being at the same time moved into position for the nextperforating operation. Meanwhile the plunger 14 has begun its upwardmovement and the spindle 18 has taken an eyelet from the raceway 70. Theupward movement of the plunger' 14 continues with the spindle 18 held inits uppermost position by the spring,"A 30 until thc end of theexpansible upsetting die is encountered by the tapered end of thespindle. The movement of the Spindle is then retarded and the spring 30yields until the upper end of the tubular holder 28 encounters theunderside of the angle piece 24. The further upward movement of theplunger 1J( then subjects the spindle 18 to the pressure of the stifferspring 32 and under its actuation the portion 20 of the spindle isforced into the u setting die expanding its sections as shown in F ig(3. In this movement the angle piece 24'en`counters the stop 36 whichpositively arrests further upward movement of the spindle, holding `gieshoulder of the spindle a slight distance A elow the ends of the diesections. The contiiiued upward movement of the plunger 14 with theinserting die 16 slides the eyelet-iupwardlv along the spindle 18 untilthe end of its barrel is Aforced against the upsetting surface whereuponthe eyclet is clenched upon the lining portion 82 of the Work as shown'in Fig. 3. During this setting operation it will be understood that theupsetting` die is maintained -in stationary position and expandedcondition.

After thc clcnching operation the pluninunediatcly lowered and the endfrom the upof the spindle 18 withdrawn setting die which immediatelyresumes its contracted condition in which it may be lacing passageWithout obstruction. The lever 48 is finally elevated and the parts ofthe machine resume their initial positions in readiness for a new evr'leof operations.

The operation of thdlmariiine has been described in connection i' iththe insertion of invisible eyelets but it will be apparent that elets orother fasteners may be readily inserted by presenting the work with thelining portion uppermost.
